Most people size their cloud storage plan around photo count, since photos feel like the bulk of what they're backing up. In practice, video is almost always the real driver of storage — a single minute of 4K video can outweigh dozens of photos, and a household with modest photo habits but a few dozen video clips a year can blow past a "generous-sounding" storage tier faster than expected.

This guide breaks down why that happens, official 2026 pricing across the major consumer providers, and a worked example. It pairs with the [data storage calculator](/calculators/data-storage-calculator), which converts your photo, video, and document counts directly into a GB/TB total and monthly cost estimate.

## Quick Answer: Why Video Dominates Storage

**Typical file sizes by content type**
| Content type | Typical size | What drives it |
| --- | --- | --- |
| Compressed photo (JPEG) | 3-6 MB | Camera resolution and compression |
| RAW photo | 20-50+ MB | Uncompressed sensor data — 5-10x a compressed JPEG |
| SD video | ~40 MB per minute | Lower resolution and bitrate |
| 1080p video | ~130 MB per minute | Standard resolution, moderate bitrate |
| 4K video | ~350 MB per minute | Roughly 2.7x the bitrate of 1080p at the same length |

A single minute of 4K video is roughly equivalent in storage to 60-115 compressed photos. This is the core reason storage estimates built around photo count alone are misleading — a household that shoots even a modest amount of 4K video (a few minutes per week from a phone) can accumulate more storage from video in a year than from thousands of photos.

> **Google and Apple have restructured tiers around AI features in 2026** — Both providers now bundle their largest storage tiers with AI features (Google AI Pro, for example) rather than offering storage-only plans at every tier. Provider pricing and tier names change; always confirm the current lineup on the official pricing page (linked in Sources below) before subscribing.

_[Figure: Provider pricing pattern at a glance — All three providers show the same shape: cost per GB drops sharply once you reach their largest common consumer tier.]_

The pattern across every provider is the same: cost per GB drops sharply at the largest common tier. At the entry-level 50-100 GB tiers, you pay roughly $0.02 per GB per month; at the 2 TB tier from Google One or iCloud+, that drops to about $0.0049 per GB per month — a 4x improvement in value. Interestingly, iCloud+'s cost per GB barely improves at all beyond 2 TB (essentially flat through the 12 TB tier), while Google One's 5 TB tier does edge out its own 2 TB tier slightly. This means it's often cheaper to jump straight to a larger tier than to pay the per-GB premium of staying on a small one, if you're likely to grow into it within a year or two anyway.

## Worked Example: A Family Photo & Video Archive

**5,000 photos (5MB avg), 200 videos (4 min avg, 1080p), 2,000 documents (150KB avg)**
| Component | Calculation | Result |
| --- | --- | --- |
| Photos | 5,000 × 5MB ÷ 1024 | 24.41 GB |
| Videos | 200 × 4 min × 130MB/min ÷ 1024 | 101.56 GB |
| Documents | 2,000 × 150KB ÷ 1,048,576 | 0.29 GB |
| Total |  | 126.26 GB (0.123 TB) |
| Monthly cost at Google One / iCloud+ 2TB rate ($0.0049/GB) | 126.26 × 0.0049 | $0.62/month |

_[Figure: Storage breakdown for the worked example — Video accounts for roughly 80% of total storage despite the household having 25x more photos than videos by count.]_

Notice that video accounts for roughly 80% of the total storage in this example despite the household having 25x more photos than videos by count. This is the video-dominance effect in practice: 200 four-minute clips at 1080p outweigh 5,000 photos by a factor of more than four to one.

## Family Sharing Changes the Math

Both Google One and iCloud+ support sharing a single storage plan across a family group, which can significantly change the effective cost-per-person even though the plan's cost-per-GB stays the same. A 2 TB plan split five ways at $9.99/month works out to roughly $2/month per person for 400 GB each — cheaper per person than any individual small-tier plan on its own. If your household has multiple people each considering a separate small plan, comparing against one shared larger plan is worth doing before committing to individual subscriptions.

## Common Storage Planning Mistakes

- Sizing a plan around photo count alone. As shown above, video length and resolution usually matter more than photo count for total storage.
- Ignoring RAW photo format sizes. If you shoot RAW (common on higher-end phone camera modes and dedicated cameras), each photo can be 5-10x the size of a standard compressed JPEG — a RAW-heavy photo library needs a very different storage estimate than a JPEG-only one.
- Not accounting for the free-tier cliff. Many providers offer a small free tier (5-15 GB is common), and automatic photo/video backup can silently exceed it within weeks of new phone use, triggering either a paid upgrade prompt or a backup failure.
- Comparing providers by sticker price at the same tier without checking cost-per-GB, especially when tiers don't line up exactly (50 GB vs. 100 GB, for example).
- Forgetting that shared family plans (where supported) can spread the cost-per-GB advantage of a larger tier across multiple people, which changes the math significantly versus separate individual plans.
- Assuming a bigger tier always has a better per-GB rate. iCloud+'s per-GB cost is essentially identical from 2TB through 12TB — there's no further volume discount to chase past that point.

## Frequently Asked Questions

**How much cloud storage do I actually need for photos and videos?**

It depends heavily on video habits more than photo count. A household with a few thousand photos and a couple hundred short videos can easily need 100+ GB, since video accounts for the majority of storage even when photos vastly outnumber videos.

**Why does video take up so much more storage than photos?**

A single minute of 1080p video is roughly equivalent to 26 compressed photos, and a minute of 4K video to about 70 photos, because video captures many frames per second at a sustained bitrate, while a photo is a single compressed image.

**Which cloud storage provider is cheapest per GB?**

At the largest common consumer tier (2 TB), Google One and iCloud+ both price at roughly $0.0049 per GB per month as of their official 2026 pricing pages, with Dropbox Plus's annual plan close behind at about $0.0059/GB. At smaller tiers, per-GB cost is noticeably higher across all providers — always verify current pricing on the official page before subscribing.

**Should I shoot in RAW if storage is a concern?**

RAW files are typically 5-10x larger than compressed JPEGs. If storage cost matters and you don't need RAW's extra editing flexibility, shooting compressed can meaningfully reduce your storage footprint.

**What is the free-tier storage cliff?**

Most providers offer a small free tier, often 5-15 GB. Automatic photo and video backup from a phone can exceed that within weeks, which either prompts a paid upgrade or causes backup to silently stop working once the limit is reached.

**Does a bigger storage tier always have a better price per GB?**

Not necessarily. iCloud+'s cost per GB is essentially flat from 2TB through 12TB, so there's no further per-GB savings from jumping to a much larger tier past that point. Google One's 5TB tier does edge out its 2TB tier slightly, but the difference is small.

**Is a family sharing plan cheaper than individual plans?**

Often yes. Splitting one larger shared plan across several family members typically works out to a lower cost per person than each person subscribing to their own smaller individual plan, since the larger plan's cost-per-GB is lower to begin with.

**How often does cloud storage pricing change?**

Periodically — providers adjust pricing and tier structures, and in 2026 both Google and Apple have introduced AI-feature bundling into their largest storage tiers. Always check the official pricing page (linked in the Sources section) rather than relying on a cached or third-party figure.

## Final Summary

Total storage = photos + videos + documents, but video is almost always the dominant term despite typically being the smallest count. Compare providers by cost-per-GB at the tier you'll actually use, not sticker price, and re-check your estimate whenever your video habits change — that's the variable most likely to blow past a plan sized around photo count alone.
